FASTENINQDEVICE.

SPECIFICATION forming part of Letters Patent N0. 65 ;,383, dated July 24, 1900).

Application filed February s, 1900, Serial mares. n.) model.)

To all whom it may concern:

Be it knownthat I, HENRY GUY CARLETON', a citizen of the United States, and a resident of New York, county of New York, and State 5 of New York, have invented certain new and useful Improvements in Fastening Devices, fully described in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in lockin g devices, and is more particularly intended for use as a window-sash fastener. The invention is, however, applicable to other uses and may be used in any place I 5 where it is desired to look a slide or other similar device which moves in ways.

One of the objects of the invention isto produce an improved locking device for use with window-sashes or other slides moving in ways in which the movable locking member will be electrically controlled.

A further object of the invention is to produce a locking device for use with windowsashes or other slides moving in ways in which the locking member is normally out of action and in which a magnet is used to.

hold the device out of action, the device be ing thrown into operation in case a movement of the slide is attempted while the magnet is inoperative. A further object of the invention is to pro duce an improved locking device for window sashes and other slides which will embody an alarm mechanism, so that if any attempt is 3 5 made to tamper with the sash or slidea noti fication thereof will be given.

With these and other objects in view the invention consists in certain constructions and in certain parts,improvements,and com- 40 binations, as will be hereinafter fully described and then more specifically pointed out in the claims hereunto appended.

In the accompanying drawings,which form a part of this specification,and in which like characters of reference indicate the same parts, Figure 1 indicates a side elevation partly in section, of a portion of a window frame and sash provided with the improved locking device. Fig. 2 is a side elevation 5e showing the parts in a different position, with the circuit closed through the alarm lmeohanism. Fig. 3is a sectionon the line 3.3 of Fig. 1.

Referring to the drawings,which illustrate a concrete embodiment of the invention as applied to a sash-fastener, 1 indicates a sashframe, and 2 indicates the window-frame in which the sash moves, the said frame being provided with ways 3, which serve to guide the sash, as is usual.

While the locking device might be located outside the window-frame and at anysuitable point along the movement ofthe sash, the window-frame 2 is preferably provided with a recess 4, in which the movable locking member and its operating parts are'contained. The recess 4 is closed by a plate 5, secured to the framein any suitable'manner, said plate being provided with a slot 6. The

movable locking member maybe variously 7o constructed. In the form shown it' consists of a hook 7, provided with an elongated slot 8, through which passesa pivot 9. Tlie'movable locking member is therefore capable of a rocking movement about its pivot auda 7 5 sliding movement with respect thereto. The locking member 7'is normally held in. such a position that the pivot 9 is at the top of the slot by means of a spring 10, which is connected to the pivot and to a point 11 on the member. i

Any suitable means may be provided with which the locking member cooperates. Preferably, however, and as in the construction shown, the sash carries aratchet12, which is provided with a plurality of teeth for a purpose to be hereinafter mentioned. The sash also preferably carries means for nor,

.mallyholding the hook in an inoperative position. While this means may be variously 9c constructed, it preferably consists of a camsurface 13, which in the construction shown is formed in one piece with the ratchet 12.

As has been indicated, the locking member or hook 7 is normally held in inoperative position. It may be thrown into engagement with the locking device on the sash in any suitable manner. In the construction shown a bearing-spring 14 is provided, said bearingspring being secured to a bracketlo'. [This bracket may be, as shown, formed 'of insulating material, or in case it is formed of metal the spring 14 will be insulated therefrom by a washer. vided for holding the locking member or book in inoperative position. Preferably, however, this will be effected by means of a magnet 18, thearmature 19 of which is carried by the locking member 7, althoughv the said member might itself form the armature for the magnet if desired. The magnet is preferably so located that its pole-piece will be close to its armature when the movable hook 7 is thrown into inoperative position by the cam-surface 13. By so arrangingthe magnet with: relation to its armature only a small magnet and little battery power is necessary to operate the locking member,since the magnet does not actually withdraw the locking member, but only holds it in inoperative position, the member being lifted into the field of the magnet by the cam-surface 13.

An alarm mechanism, which may consist of the usual electric bell 20, is provided, and the alarm mechanism is preferably so arranged that the circuit thereof will be controlled by the locking member.

-Any suitable circuit or circuits may be employed for the devices thus far described. In the construction shown the battery is indicated at 21, said battery being connected by a'wire 22 with any suitable circuit-closing device-such, for instance, as a push-button 23. From the push-button 23 a wire 24 leads to the coils of the magnet, and the circuit then runs by the metallic portions of the lock to a binding-stud 25, mounted on the movable member 7. From the binding-stud 25 a wire 26 leads to the battery.

7 The alarm-circuit shown is formed by a branch wire 27, which leads from the wire 22 to the bell. From the bell a wire 28 leads to a spring-contact 29, which is carried on the bracket 15 before described. This spring-contact 29 is normally out of contact with the stud 25, but lies in the path of said stud, so that the circuit will be closed when the looking member is given the sliding movement on its pivot before described.

The operation of the construction is as follows: The normal condition of the parts is shown in Fig. 1. If it be desired to open the window, the push-button 23 is depressed,

closing the circuit through the magnet by the wires 22 24, the lock-casing, and the wire 26. As has been before indicated, the movable locking-hook 7 is held in the field of the magnet by means of the cam-surface 13. When the circuit is closed, as before described, the magnet attracts its armature 19 and the looking member is held in inoperative position, so that the sash is free to move and carry the ratchet 12 by the point of the hook. If, however, an attempt be made to move the sash when the magnet is deenergized, the parts will be thrown into the position indicated in Fig. 2. In this position it will be seen that a slight upward movement of the sash will cause the hook to ride off the cam-surface 13 Any suitable means may be proand to engage the upper tooth of the ratchet 12. A farther movement of the sash causes the movable member to slide upward on its pivot and brings the stud 25 against the spring-contact 29. This closes the circuit, the current going from the battery by the wires 22 27 through the hell, by the wire 28 to the contact 29, and from the binding-stud 25 by the wire 26 back to the battery 21. The alarm is thus sounded and continues to sound until the sash is restored to its original position and the hook drawn back by the spring 10, so that the stud 25 is moved away from the contact 29.

By providing the ratchet with a number of teeth, as shown, it will be seen that the sash may be'locked in any desired position. In the construction shown the ratchet is provided with three teeth; but this number may be increased, if desired. If, for instance, it be desired to lock the sash in a position in which the window is partly open, the circuit is closed and the sash raised until the hookis opposite one of the teeth of the ratchetsay, for instance, the third tooth. The circuit is now broken and the spring 14 throws the locking-hook inward, so that it overlaps the ratchet-tooth. Inasmuch as the book was out of engagement with the sash when the same was raised, it was given no sliding While the invention is shown as embodied,

in a sash-fastener, it is to be understood that it has a much wider application. It might,

for instance, be used to lock vertically-slid ing elevator-doors, the sliding covers of desks, and, in fact, to look any slide which has a movement in ways. It is to be understood, furthermore, that the specific construction by which the invention is carried into effect may be considerably varied. The invention is not, therefore, to be limited to the specific details of construction which have been hereinabove described.
